Changes in industrial energy use from transportation sector transformations

Tags


Transformations in the transportation sector will save 7 quads/y of refining energy. Half that saving will be used to produce biofuels, hydrogen, and carbon fiber. The net reduction in 2050 industrial energy use will be about 3.5 quads/y.
